* Make filament compatibility temperature-aware
Extend filament compatibility checks to consider actual nozzle temperatures and temperature ranges.
Print::check_multi_filaments_compatibility now accepts nozzle temperatures and range lows/highs; it resolves missing ranges from material defaults, computes per-filament effective temperatures, and checks pairwise compatibility (including high/low/mid mixed cases).
Updated callers in Print::check_multi_filament_valid and CalibrationWizardPresetPage to pass nozzle settings, consolidated user-facing warning strings, and fixed extruder index handling and minor logic/path improvements.
Clarify incompatible nozzle temperature warnings
* Update Print.cpp
* Remove json usage
* Reduce messages
* Add safety checks and add logic to avoid creating degenerate polygons in contour_extrusion_path
* fix comment
* fix(zaa): cast from slice_z upward only, guard normal on miss
* remove old code

* fix: manual filament change not emitting MANUAL_TOOL_CHANGE for BBL printers
BBL-specific M1020 S handling in toolchange() bypassed toolchange_prefix(),so manual_filament_change had no effect — M1020 was always emitted regardless of the setting. Move the BBL logic into toolchange_prefix() so all callers respect the option consistently.

Fix extrusion of some support layers at wrong Z height
Fixes the issue that PR #12736 (github.com/OrcaSlicer/OrcaSlicer/pull/12736) reverted the changes of PR #13327 (github.com/OrcaSlicer/OrcaSlicer/pull/13327)
This PR supersedes #12225, which originally proposed this feature but
appears inactive.
The feature originated from work I developed earlier in
[BambuStudio-ZAA](https://github.com/adob/BambuStudio-ZAA), a private
fork of Bambu Studio
Compared to #12225, I updated the implementation for current upstream
and fixed the following issues:
- fixed broken tests
- removed references to nonplanar directory
Reviewers may want to compare against #12225 for earlier
discussion/context.
## Summary
Port of **Z Anti-Aliasing (ZAA)** from
[BambuStudio-ZAA](https://github.com/adob/BambuStudio-ZAA) to
OrcaSlicer.
ZAA eliminates visible stair-stepping on curved and sloped top surfaces
by raycasting each extrusion point against the original 3D mesh and
micro-adjusting its Z height to follow the actual surface geometry. The
result is visibly smoother domes, chamfers, and shallow slopes — without
post-processing.
## How It Works
1. The slicer runs normally, then a **posContouring** step processes
each layer
2. `ContourZ.cpp` raycasts every extrusion point vertically against the
source mesh
3. Each point's Z is adjusted to the mesh intersection, converting flat
`Polyline` paths into `Polyline3` paths with per-point Z coordinates
4. The G-code writer emits the adjusted Z values, so the printer follows
the true surface
## Configuration
Five new settings under **Print Settings > Quality**:
| Setting | Type | Default | Description |
|---------|------|---------|-------------|
| `zaa_enabled` | bool | off | Master enable/disable switch |
| `zaa_min_z` | float | 0.06 mm | Minimum Z layer height; controls
slicing plane offset |
| `zaa_minimize_perimeter_height` | float | 35° | Reduce perimeter
heights on slopes below this angle (0 = disabled) |
| `zaa_dont_alternate_fill_direction` | bool | off | Keep fill direction
consistent instead of alternating |
| `zaa_region_disable` | bool | off | Disable ZAA for a specific print
region/material |
## Key Changes
- **Core algorithm**: New `src/libslic3r/ContourZ.cpp` (~330 lines) —
raycasting engine
- **3D geometry**: `Point3`, `Line3`, `Polyline3`, `MultiPoint3` extend
existing 2D types
- **Arc fitting**: Templated to work with both 2D and 3D geometry
- **Pipeline**: `ExtrusionPath::polyline` changed from `Polyline` to
`Polyline3`; new `posContouring` step in `PrintObject.cpp`
- **G-code**: `GCode.cpp` writes per-point Z when `path.z_contoured` is
set
- **UI**: ZAA settings exposed in Print Settings > Quality panel
- **Documentation**: `docs/ZAA.md` with usage and implementation details
57 files changed, ~1800 insertions, ~200 deletions.
## Test Plan
- [ ] Load a model with curved top surfaces (sphere, dome, chamfered
box)
- [ ] Enable **Z contouring** in Print Settings > Quality
- [ ] Slice and verify G-code has varying Z values within contoured
layers
- [ ] Build on macOS (verified), test on Linux and Windows
* Add OrcaCloud sync platform and preset bundle sharing system
Introduce OrcaCloud, a cloud sync platform for user presets, alongside
a preset bundle system that enables sharing printer/filament/process
profiles as local exportable bundles or subscribed cloud bundles.
OrcaCloud platform:
- Auth to Orca Cloud
- Encrypted token storage (file-based or system keychain)
- User preset sync with
- Profile migration from default/bambu folders on first login
- Homepage integration with entrance to cloud.orcaslicer.com
Preset bundles:
- Local bundle import/export with bundle_structure.json metadata
- Subscribed cloud bundles with version-based update checking
- Thread-safe concurrent bundle access with read-write mutex
- Canonical bundle preset naming (_local/<id>/... and _subscribed/<id>/...)
- Bundle presets are read-only; grouped under subheaders in combo boxes
- PresetBundleDialog with auto-sync toggle, refresh, update notifications
- Hyperlinked bundle names to cloud bundle pages

Fix fan speed staying high
When fan speed-up time is enabled, layers can inherit a higher fan speed than intended.
If a layer ended with a role-driven fan change, the last applied fan speed
was not properly tracked. As a result, the next layer could start with an
incorrect fan state and keep the higher speed until another fan command
overrode it.
Ensure the emitted fan speed is always tracked correctly, including when
flushing buffered commands at the end of a layer.
* Fix: Enable instance collision detection in GCode and Print clearance
Squashed commit containing:
- Fix gcode path conflict detection in ConflictChecker.cpp by iterating all instances.
- Improve clearance validation in Print.cpp by calculating convex hulls per instance (fixes scaling/mirroring issues).
- Added // Orca: comments to mark changes.
* Fix Wipe Tower G-code conflict detection for WipeTower2
* Fix: Improve object/instance selection for collision and validation warnings
- Updated validation logic in Print.cpp to report specific ModelInstance instead of ModelObject for collision/clearance warnings.
- Updated NotificationManager and Plater to handle ModelInstance selection in 'Jump to' links.
- Added fallback to object selection if specific instance cannot be selected.
- Included fixes for G-code conflict detection (ConflictChecker, GLCanvas3D) to also report instances.
- Improved GUI_ObjectList to update canvas selection when items are selected via API.
* Fix: Prevent crash when loading .3mf projects
Moved update_selections_on_canvas() out of ObjectList::select_items() to avoid premature UI updates during loading. Canvas updates are now explicitly called in NotificationManager and Plater callbacks where needed.
* Fix: Address code review comments
- Fix memory allocation for extrusion layers deep copy
- Remove unused variable in GLCanvas3D
- Fix string formatting crash risk in NotificationManager
- Remove dead code in Plater

* Add extrusion role change G-code options
Introduces new G-code options for handling extrusion role changes at the process and filament levels. Updates configuration, GUI, and GCode logic to support 'process_change_extrusion_role_gcode' and 'filament_change_extrusion_role_gcode', allowing custom G-code insertion when the extrusion role changes.

* Optimize extrusion role-change gcode handling
Cache gcode template strings and current filament id, and guard creation of DynamicConfig/placeholder processing behind a check that at least one role-change gcode is non-empty. This avoids redundant config lookups and DynamicConfig/placeholder parsing when no custom role-change gcode is defined, improving clarity and performance without changing behavior.
